Bursting oscillation of simply supported fluid-conveying pipes

The main purpose of this article is to explore an originality multiple-frequency bursting of simply-supported fluid-conveying pipes with initial micro-bending shape under different low-frequency excitation conditions. Based on the Galerkin's method and the fast-slow dynamics analysis method, rich vibration phenomena are observed with different excitation conditions, and the multi-valued characteristics are verified by the domain of attraction. The results demonstrate that low-frequency excitation can cause complex dynamical phenomena of the fluid-conveying pipes.
